How to match Zen and Phpbb template?

I am working on creating a style for my store that fits it's theme and want to try to create a match Phpbb template for it. Is there a way to make both look the same? Even if it is just color help that would be great.
I am currently reworking my website to make it look more professional so right now just have the Mostly Grey template installed and would like something similar, but not as Dark

I would also like to match my zen cart template to my phpbb does anyone know the answer?

There are some really nice free phpBB skins available.
Here's a tie I use: phpbb3styles.net
Pick one you like, then modify it to match your site (bring in your logo, header_bg and if you really want to go nuts - change all the buttons) :D
